What is an HDMI cable?

An HDMI cable (High-Definition Multimedia Interface cable) is a condensed audio/video interface which sends uncompressed digital data.

It is a digital alternative to analogue, for example radio frequency coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, or VGA.

An HDMI  cable connects digital audio/video source, including HD DVD players, Blu-ray Disc players, etc to relevant digital audio machines and computer monitors, projectors, etc.

On just one cable, HDMI is able to send up to 8 channels of compressed or uncompressed digital audio. HDMI is electrically relevant to  Digital Visual Interface (DVI), conversion is unnecessary and there is no loss quality when a DVI-to-HDMI adapter is used.

HDMI products became popular in 2003 and over 850 consumer electronics and PC companies have taken up HDMI spec.
